This page gives you information about syntax to build wiki-tables in MediaWiki.
To convert from spreadsheets such as Gnumeric, MS Excel or OpenOffice.org Calc, go here.
You can use the Mediawiki edit toolbar to create tables on wikipedia, and some wikimedia projects. It is helpful to generate the necessary codings. However on many MediaWiki wikis (and by default) the table tool is not available. To Do: Link to enable Tables on MediaWikis.
Use the first button on the right of the toolbar to insert a table when editing a page.
By default, it includes the following text:
{| class="wikitable"
|-
! header 1
! header 2
! header 3
|-
| row 1, cell 1
| row 1, cell 2
| row 1, cell 3
|-
| row 2, cell 1
| row 2, cell 2
| row 2, cell 3
|}
| Column heading 1 | Column heading 2 | Column heading 3 |
|---|---|---|
| Row heading 1 | Cell 2 | Cell 100 |
| Row heading A | Cell B | Cell C |
Although HTML table syntax also works, special wikicode can be used as a shortcut to create a table. The pipe (vertical bar) codes function exactly the same as HTML table markup, so a knowledge of HTML table code will help in understanding pipe code. The shortcuts are as follows:
{| to begin a table, and |} to end it. Each one needs to be on its own line:{| table code goes here |}
|+" and the caption after it:
{|
|+ caption
table code goes here
|}
|-". The codes for the cells in that row will start on the next line.
{|
|+ The table's caption
|-
cell code goes here
|-
cell code goes here
|}
{|
|+ The table's caption
|-
| cell codes go here
|-
| cells in the next row go here
| more cells in the same row here
|}
{|
|+ The table's caption
|-
|Cell 1 || Cell 2 || Cell 3
|-
|Cell A
|Cell B
|Cell C
|}
{| border="1"
|-
|format modifier (not displayed)|These all |(including the pipes)|go into |the first cell
|-
|}
which is probably not what you want:
| These all |(including the pipes)|go into |the first cell |
However, the format modifier is useful:
{| border="1"
|-
|Cell 1 (no modifier - not aligned)
|-
|align="right" |Cell 2 (right aligned)
|-
|}
| Cell 1 (no modifier - not aligned) |
| Cell 2 (right aligned) |
Just remember: no more than 2 single pipes on a line!
{|
|+ The table's caption
! Column heading 1 !! Column heading 2 !! Column heading 3
|-
|Cell 1 || Cell 2 || Cell 3
|-
|Cell A
|Cell B
|Cell C
|}
{|
|+ The table's caption
! Column heading 1 !! Column heading 2 !! Column heading 3
|-
! Row heading 1
| Cell 2 || Cell 3
|-
! Row heading A
|Cell B
|Cell C
|}
{| border="1"
|+ The table's caption
! Column heading 1 !! Column heading 2 !! Column heading 3
|-
! Row heading 1
| Cell 2 || Cell 3
|-
! Row heading A
|Cell B
|Cell C
|}
The final table would display like this:
The table's caption Column heading 1 Column heading 2 Column heading 3 Row heading 1 Cell 2 Cell 3 Row heading A Cell B Cell C
The table parameters and cell parameters are the same as in HTML, see [1] and Table (HTML). However, the thead, tbody, tfoot, colgroup, and col elements are currently not supported in MediaWiki.
A table can be useful even if none of the cells have content. For example, the background colors of cells can be changed with cell parameters, making the table into a diagram, like m:Template talk:Square 8x8 pentomino example. An "image" in the form of a table is much more convenient to edit than an uploaded image.
Each row must have the same number of cells as the other rows, so that the number of columns in the table remains consistent. For empty cells, use the non-breaking space as content to ensure that the cells are displayed. To show a visible pipe in a cell, use <nowiki>|</nowiki> or |.
With colspan and rowspan cells can span several columns or rows, see the Mélange example below. However, this has the disadvantage that sorting does not work properly anymore.
Both of these generate the same output. Choose a style based on the number of cells in each row and the total text inside each cell.

Two ways of specifying color of text and background for a single cell are as follows. The first form is preferred:
Wiki markup
{|
| style="background:red; color:white" | abc
| def
| bgcolor="red" | <font color="white"> ghi </font>
| jkl
|}
What it looks like in your browser
abc def ghi jkl
Like other parameters, colors can also be specified for a whole row or the whole table; parameters for a row override the value for the table, and those for a cell override those for a row:
Wiki markup
{| style="background:yellow; color:green"
|-
| abc || def || ghi
|- style="background:red; color:white"
| jkl || mno || pqr
|-
| stu || style="background:silver" | vwx || yz
|}
What it looks like in your browser
abc def ghi jkl mno pqr stu vwx yz
To make the table blend in with the background, use style="background:none" or style="background:transparent". (Warning: style="background:inherit", does not work with some browsers, including IE6!)
See : style, background, list of colors, web colors
The width and height of the whole table can be specified, as well as the height of a row. To specify the width of a column one can specify the width of an arbitrary cell in it. If the width is not specified for all columns, and/or the height is not specified for all rows, then there is some ambiguity, and the result depends on the browser.
Wiki markup
{| style="width:75%; height:200px" border="1"
|-
| abc || def || ghi
|- style="height:100px"
| jkl || style="width:200px" |mno || pqr
|-
| stu || vwx || yz
|}
What it looks like in your browser
abc def ghi jkl mno pqr stu vwx yz
Note that style="inline CSS" has no effect with some browsers. If compatibility is important, equivalent older constructs like width="75%" should work on more browsers.
If you wish to force column widths to your own requirements, rather than accepting the width of the widest text element in a column's cells, then follow this example. Note that wrap-around of text is forced.
{| border="1" cellpadding="2"
!width="50"|Name
!width="225"|Effect
!width="225"|Games Found In
|-
|Poké Ball || Regular Poké Ball || All Versions
|-
|Great Ball || Better than a Poké Ball || All Versions
|}
Name Effect Games Found In Poké Ball Regular Poké Ball All Versions Great Ball Better than a Poké Ball All Versions
To set column widths in a table without headers, specify the width in the first cell for each column, like this:
{| border="1" cellpadding="2"
|-
|width="100pt"|This column is 100 points wide
|width="200pt"|This column is 200 points wide
|width="300pt"|This column is 300 points wide
|-
|blah || blih || bluh
|}
This column is 100 points wide This column is 200 points wide This column is 300 points wide blah blih bluh
One application of setting the widths is aligning columns of consecutive tables:
| Country | Capital |
|---|---|
| The Netherlands | Amsterdam |
| Country | Capital |
|---|---|
| France | Paris |
By default data in tables is vertically centrally aligned, which results in odd-looking layouts like this:
Row heading A longer piece of text. Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum. A shorter piece of text. Row heading A longer piece of text.Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum. A shorter piece of text.
To fix this, apply the valign="top" attribute to the rows (unfortunately it seems to be necessary to apply this individually to every single row). For example:
{| border="1" cellpadding="2"
|-valign="top"
|width="10%"|'''Row heading'''
|width="70%"|A longer piece of text. Lorem ipsum...
|width="20%"|A shorter piece of text.
|-valign="top"
|'''Row heading'''
|A longer piece of text. Lorem ipsum...
|A shorter piece of text.
|}
Row heading A longer piece of text. Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum. A shorter piece of text. Row heading A longer piece of text.Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum. A shorter piece of text.
One can position the table itself, and all contents in a row, and contents in a cell, but not with a single parameter for all contents in the table, see m:Template talk:Table demo. Do not, under any circumstances, use "float" to position a table. It will break page rendering at large font sizes.
Here's a more advanced example, showing some more options available for making up tables. Note however that with colspan and rowspan sorting does not work properly anymore.
You can play with these settings in your own table to see what effect they have. Not all of these techniques may be appropriate in all cases; just because you can add colored backgrounds, for example, doesn't mean it's always a good idea. Try to keep the markup in your tables relatively simple -- remember, other people are going to be editing the article too! This example should give you an idea of what is possible, though.

Five different (blue) tables are shown nested inside the cells of a table. Automatically the two tables |A| and |B|B| are vertically aligned instead of the usual side by side of text characters in a cell. "float" is used to fix each of tables |C| and |D| to their own position within one cell of the table. This may be used for charts and schemes. Nested tables must start on a new line.

Note that using rowspan="2" for cell G combined with rowspan="3" for cell F to get another row below G and F won't work, because all (implicit) cells would be empty. Likewise complete columns are not displayed if all their cells are empty. Borders between non-empty and empty cells might be also not displayed (depending on the browser), use to fill an empty cell with dummy content.
Centered tables can be achieved, but they will not "float"; that is to say, no text will appear to either side. The trick is {| style="margin: 1em auto 1em auto"
Wiki markup
{| class="wikitable" style="margin: 1em auto 1em auto"
|+ '''Cells left-aligned, table centered'''

At the start of a cell, add your parameter followed by a single pipe. For example width="300"| will set that cell to a width of 300 pixels. To set more than one parameter, leave a space between each one.

A method to get columns of numbers aligned at the decimal point is as follows:
Wiki markup
{| cellpadding="0" cellspacing="0"
|align="right"| 432 || .1
|-
|align="right"| 43 || .21
|-
|align="right"| 4 || .321
|}
What it looks like in your browser
432 .1 43 .21 4 .321
If the column of numbers appears in a table with cell padding or cell spacing, one can still align the decimal points without an unsightly gap in the middle. Embed a table in each number's cell and specify its column widths. Make the embedded tables' column widths the same for each cell in the column. (If decimal points are still misaligned using this method, the main table's column may be too narrow. Add a parameter to increase the column's width.)
Wiki markup
{|border="1" cellpadding="4" cellspacing="2"
|
{|cellpadding="0" cellspacing="0" width="100%"
|align="right" width="50%"| 432 ||width="50%"| .1
|}
|-
|
{|cellpadding="0" cellspacing="0" width="100%"
|align="right" width="50%"| 43 ||width="50%"| .21
|}
|-
|
{|cellpadding="0" cellspacing="0" width="100%"
|align="right" width="50%"| 4 ||width="50%"| .321
|}
|}
What it looks like in your browser
432 .1
43 .21
4 .321
In simple cases one can dispense with the table feature and simply start the lines with a space, and put spaces to position the numbers:
432.1 43.21 4.321
In the first line of table code, after the "{|", instead of specifying a style directly one can also specify a CSS class. The style for this class can be specified in various ways:
Instead of remembering table parameters, you just include an appropriate style class after the {|. This helps keep table formatting consistent, and can allow a single change to the class to fix a problem or enhance the look of all the tables that are using it at once. For instance, this:
|
|
|||||||||||||||||||||||||
| becomes this: | ||||||||||||||||||||||||||
|
|
|||||||||||||||||||||||||
simply by replacing inline CSS for the table by class="wikitable". This is because the wikitable class in MediaWiki:Common.css contains a number of table.wikitable CSS style rules. These are all applied at once when you mark a table with the class. You can then add additional style rules if desired. These override the class's rules, allowing you to use the class style as a base and build up on it:
Wiki markup
{| class="wikitable" style="font-style:italic; font-size:120%; border:3px dashed red;"
|+Multiplication table
|-
! × !! 1 !! 2 !! 3
|-
! 1

What it looks like in your browser
Multiplication table × 1 2 3 1 1 2 3 2 2 4 6 3 3 6 9 4 4 8 12 5 5 10 15
Notice that the table retains the gray background of the wikitable class, and the headers are still bold and centered. But now the text formatting has been overridden by the local style statement; all of the text in the table has been made italic and 120% normal size, and the wikitable border has been replaced by the red dashed border.
Of course this works only for browsers supporting inline CSS, if it's important use XHTML markup like <big> instead of "font-size:120%", or Wiki markup like ''text'' instead of "font-style:italic".
Tables can be made sortable by adding class="sortable"; for details see Help:Sorting. Since this can be very useful, it is wise to keep the possibilities and limitations of this feature in mind when designing a table. For example:
A long form of abbreviated content can be put as legend outside the table.
Wiki markup

Regardless of whether wikitable format or HTML is used, the wikitext of the rows within a table, and sometimes even within a collection of tables, has much in common, e.g.:
In that case it can be useful to create a template that produces the syntax for a table row, with the data as parameters. This can have many advantages:
Example:
Using m:help:table/example row template (talk, backlinks, edit)
{| class="wikitable sortable"
|-
! a
! b
! a/b
{{help:table/example row template| 50|200}}
{{help:table/example row template| 8| 11}}
{{help:table/example row template|1000| 81}}
|}
gives:
| a | b | a/b |
|---|---|---|
| 50 | 200 | 0.25 |
| 8 | 11 | 0.72727272727273 |
| 1000 | 81 | 12.345679012346 |
For a conditional row in a table, we can have:
{| class=wikitable
{{ #if:1|{{!}}- <!-- Row one will be shown because the '1' evaluates to TRUE -->
! row one, column one
{{!}}row one, column two}} <!-- {{!}}'s get evaluated to the pipe character '|', i.e. template:! just contains '|' -->
{{ #if: |{{!}}- <!-- Row two NOT shown because the space between the ':' and the '|' evaluates to FALSE -->
! row two, column one
{{!}}row two, column two}}
|- <!-- Row three will be shown -->
! row three, column one
| row three, column two
|}
Which gives the following table: (note how the second row is missing)
| row one, column one | row one, column two |
|---|---|
| row three, column one | row three, column two |
Other types of table syntax that MediaWiki supports:
All three are supported by MediaWiki and create (currently) valid HTML output, but the pipe syntax is the simplest. Also, HTML & wiki-<td> syntax (i.e., unclosed <td> and <tr> tags) will not necessarily remain browser-supported in the upcoming future, especially on handheld internet-accessible devices.
See also Table (HTML), HTML element#Tables. Note however that the thead, tbody, tfoot, colgroup, and col elements are currently not supported in MediaWiki.

See also Template talk:For#Tables.
The pipe syntax, developed by Magnus Manske, substitutes pipes (|) for HTML. There is an on-line script which converts html tables to pipe syntax tables.
The pipes must start at the beginning of a new line, except when separating parameters from content or when using || to separate cells on a single line. The parameters are optional.
A table is defined by {| ''params'' |} which equals <table ''params''>Insert non-formatted text here </table>
<tr> tags will be generated automatically for the first row. To start a new row, use
|-
which results in
<tr>
Parameters can be added like this:
|- params
which results in
<tr params>
Note:
Cells are generated either like this:
|cell1 |cell2 |cell3
or like this:
|cell1||cell2||cell3
which both equal
<td>cell1</td><td>cell2</td><td>cell3</td>
so "||" equals "newline" + "|"
Parameters in cells can be used like this:
|params|cell1||params|cell2||params|cell3
which will result in
<td params>cell1</td> <td params>cell2</td> <td params>cell3</td>
Functions the same way as TD, except "!" is used instead of the opening "|". "!!" can be used instead of "||". Parameters still use "|", though! Example:
!params|cell1
A <caption> tag is created by
|+ Caption
which generates
<caption>Caption</caption>
You can also use parameters:
|+ params|Caption
which will generate
<caption params>Caption</caption>

In most cases, when a code line is longer than the web browser window's width, then a scrolling bar appears at bottom, to let the viewer slide to the right side (and also left side) to see the rest of the codes, because, the use of <pre> tag causes the code line to remain intact, unless an EOL (CR/LF) hidden character is reached in that text line. But having to slide or scroll to the right or left for viewing the full codes is often not comfortable to many readers. To solve such problem, using the <p>, <tt> and <br /> HTML tags, are better than using the <pre> tag, as those will limit the length of a line of code according the available space in the web browser's window and therefor will not result in the need to move the scroll-bar right (or left) for viewing. By placing the codes inside the <tt>...</tt> HTML tags, codes are displayed with a fixed width text/font, (like the <pre> tag uses) for easier reading. HTML tag <br /> is used to display (or bring) next line of codes, starting from the next line. HTML tag <p> along with its CSS style properties, is used to create the blue colored dashed bordered rectangular box (Code box) around the codes, (like the HTML <pre> tag, which gets these properties from the main.css stylesheet file).
An example of table code with a long line is:
{| border="5" cellspacing="5" cellpadding="2"
| style="text-align: center;" | [[Image:gnome-system.png]]
|-
! Computer
|-
| style="color: yellow; background-color: green;" | Processor Speed: <span style="color: white;"> 1.8 GHz </span>
|}
producing the below table:
| Computer |
|---|
| Processor Speed: 1.8 GHz |
Code box above the table has the auto line wrapping feature enabled. Note the long line (the sixth line from top) inside the codes, which is wrapped inside the Code box. This Code box and the codes, can be displayed by using below codes in the edit box.
<p style="padding: 1em; border: 1px dashed #2f6fab; color: Black; background-color: #f9f9f9; line-height: 1.1em;"> <tt>
<nowiki>{|</nowiki> border="5" cellspacing="5" cellpadding="2" <br />
| style="text-align: center;" | <nowiki>[[</nowiki>Image:gnome-system.png]] <br />
|- <br />
! Computer <br />
|- <br />
| style="color: yellow; background-color: green;" | Processor Speed: <nowiki><span style="color: white;"></nowiki> 1.8 GHz <nowiki></span></nowiki> <br />
<nowiki>|}</nowiki> <br />
</tt> </p>
See the above codes, note that, <nowiki>...</nowiki> tags were used to disable wiki markup codes for beginning a table ({|), ending a table (|}), start of an image displaying ([[), or a hyperlink, etc. All wiki & HTML markup codes need to be disabled by enclosing them inside the <nowiki>...</nowiki> tags. If these codes were to be displayed inside another table, then, each | (pipe) & ! (Exclamation mark) symbol also needed to be enclosed inside the <nowiki> tags. Note that, the longer line is automatically wrapped according to the width of the web browser's window, inside the Code box.
Alternatively, we can replace each | (pipe symbol) character with | (HTML decimal entity code), replace each ! (exclamation mark) with ! code, replace { (beginning curly/second bracket) with { and we may replace } (closing curly/second bracket) with } code. Also replace the < (less than sign, or beginning angle bracket) with < numeric entity code or, replace it with < (HTML symbol entity code). For more on HTML decimal or hexadecimal numeric entity codes, please see w:Windows Alt codes. To display the wiki image markup code, we should replace the [ (beginning square/third bracket) with [ and we may replace ] (closing square/third bracket) with ]. When we are replacing characters with their numeric enitity codes, we are actually disabling their normal functionality, so we can display them on the web page(s).

To format for a square monitor or window, use a tape measure. Determine the height of your rectangular screen. Using that figure measure under the screen to determine the width your monitor’s screen would be if it were square. Mark that location using ink or tape under the screen. Drag the side of your browser’s window to that location so the window is square based on accurate measurements. Square monitors and reading windows are not able to contain tables and galleries made for rectangular and wide screens. When a table or gallery is wider than the monitor, it makes every line of text wider than the screen as well. The px amounts of the following gallery were determined after measuring the window to make sure it was square:

For this:
A wikitable can be used to display side-by-side images, in the manner of an image gallery (formatted by "<gallery>"), but with larger images and less vacant area around photos.
A simple framed gallery can be formatted using class="wikitable" to generate the minimal thin-lines around images/photos within the table:
{| class="wikitable"
|-
|<!--column1-->[[Image:Worms 01.jpg|265px]]
|<!--column2-->[[Image:Worms Wappen 2005-05-27.jpg|235px]]
|-
|<!--column1-->Nibelungen Bridge to Worms<br/>across the [[Rhine]]
|<!--column2-->Worms and its sister cities
|}<!--end wikitable-->
Note the result below (with thin-lined cells):
| Nibelungen Bridge to Worms across the Rhine |
Worms and its sister cities |
Another issue about the standard "<gallery>" tag, in 2007, was that it put 4 images per line, overrunning the right margin of a wiki article, unless the gallery was stopped at 3 images. However, a wikitable uses typical image-links with sizes, such as "[[Image:XXX.jpg|130px]]" so 4 images could be displayed on a wikitable line within a 600px width (for 800x600 resolution screens).
{| class="wikitable"
|-
|<!--col1-->[[Image:Worms 01.jpg|130px]]
|<!--col2-->[[Image:Worms Wappen 2005-05-27.jpg|125px]]
|<!--col3-->[[Image:Liberty-statue-with-manhattan.jpg|125px]]
|<!--col4-->[[Image:New-York-Jan2005.jpg|125px]]
|-
|<!--col1-->Nibelungen Bridge to Worms
|<!--col2-->Worms and its sister cities
|<!--col3-->Statue of Liberty
|<!--col4-->New York City
|}<!--end wikitable-->
| Nibelungen Bridge to Worms | Worms and its sister cities | Statue of Liberty | New York City |
Another advantage about wikitable images, compared to "<gallery>" formatting, is the ability to "square" each image when similar heights are needed, so consider putting 2-number image sizes (such as "199x95px"), where the 2nd number limits height:
{| class=wikitable
|-
|<!--col1-->[[Image:Liberty-statue-with-manhattan.jpg|199x95px]]
|<!--col2-->[[Image:New-York-Jan2005.jpg|199x95px]]
|<!--col3-->[[Image:Gold star on blue.gif|199x95px]]
|<!--col4-->[[Image:Worms 01.jpg|100x95px]]<!--smaller-->
|-
|<!--col1-->Statue of Liberty
|<!--col2-->New York City
|<!--col3-->Star on blue
|<!--col4-->Bridge to Worms
|}<!--end wikitable-->
Note the 3 images sized "199x95px" appear identical height, of 95px (4th image purposely smaller). The "95px" forces height, while "199x" fits the various widths (could even be "999x"):
![]() |
|||
| Statue of Liberty | New York City | Star on blue | Bridge to Worms |
Therefore, the use of size "199x95px" (or "999x95px") produces the auto-height-sizing beyond the "<gallery>" tag, and with the option to set taller thumbnails ("199x105px"), or even to have some images purposely smaller than other images of "95px" height. A very short height ("70px") allows many more images across the table:
{| class=wikitable
|-
|<!--col1-->[[Image:Liberty-statue-with-manhattan.jpg|199x70px]]
|<!--col2-->[[Image:Gold star on blue.gif|199x70px]]
|<!--col3-->[[Image:New-York-Jan2005.jpg|199x70px]]
|<!--col4-->[[Image:Gold star on deep red.gif|199x70px]]
|<!--col5-->[[Image:Worms 01.jpg|199x70px]]<!--same height-->
|<!--col6-->[[Image:Gold star on blue.gif|199x70px]]
|}
The above wikitable-coding produces the result below, of 6 columns:
![]() |
![]() |
![]() |
Once images have been placed in a wikitable, control of formatting can be adjusted when more images are added.
Images within a wikitable can be shifted by inserting non-breaking spaces (" ") before or after the image-link (" [[Image:]]"). However, auto-centering simply requires use of center-tags to be placed around an image-link for centering in a cell ("<center>[[Image:..]]</center>").
In the example below, note how Col2 uses <center>, but Col3 uses " ":
{| class=wikitable
|-
|<!--Col1-->[[Image:Domtoren_vanaf_Brigittenstraat.jpg|299x125px]]
|<!--Col2--><center>[[Image:Utrecht 003.jpg|299x125px]]</center>
|<!--Col3--> [[Image:Uitzicht--Domtoren.jpg|299x125px]]
|-
|<!--Col1-->Dom tower from Brigittenstraat
|<!--Col2-->Cloister garth of the Utrecht Dom Church
|<!--Col3--> <small>View from bell tower</small>
|}
The above coding generates the table below: note the middle garden image is centered (but not the left image), and the right image has 2 spaces before " View...":
|
|
|
|
| Dom tower from Brigittenstraat | Cloister garth of the Utrecht Dom Church | View from bell tower |
Also note that tag "<small>" made a smaller text-size caption.
Sometimes, the larger wikitable images are much faster (3x-8x faster) than formatting the smaller <gallery> images, contrary to the notion that "smaller images should use less data" (not always true). It is not easy to predict why wikitables (with larger images) are so much faster: perhaps older gallery images were thumbnailed as larger data-blocks, but when reformatted as larger images for a wikitable, the new (larger) thumbnails become 3x-8x more streamlined, so 3x-8x faster in data transfer than <gallery> images.
However, actual transfer/display speeds depend on the individual files. In October 2007, PNG-format files often stored as 5%-10% slightly smaller than equivalent GIF files, but upon wiki-thumbnailing, the PNG files were converted to massive high-resolution form, where a PNG-format image became a gargantuan data file, often 9x-21x times heavier (more data) than a similar JPEG thumbnail. However, even the quick JPEG photo images might become another 3x-8x faster in a wikitable, rather than as <gallery> images.
|
In this gallery, the left 120x90 thumbnail has file-size: 43925b, ~8x slower than the larger wikitable image above, 167x125 with file-size 5693 bytes. Garden image is 22823b v. 8175b in the wikitable (data sizes Jan. 2008).
|
Transfer display speeds are difficult to predict, so beware standardizing any image format as better or "faster" than another. Whereas a trimmed, full-size PNG file might display 10% faster than a full-size GIF file, the thumbnailed PNG was typically 4x slower than GIF thumbnails, while PNG was 9x-21x times slower than JPEG thumbnails.
The most important issue is that wikitable-images can be larger, clearer than <gallery> images, more important than some wikitable images being 3x-8x faster than the smaller gallery images.
